How can I display the names of elements stored in an object in Julia? For example, in R, we have the command `names()` which displays the names of those elements. In Julia, the command `eigen(A)` stores the eigenvalues in `values` and the eigenvectors in `vectors`, but I had to look for the github page of the `eigen` command to know that. Isn’t there a command in Julia to know those names directly? Thank you!

[`fieldnames(typeof(A))`](https://docs.julialang.org/en/v1/base/base/#Base.fieldnames)

Ah thank you! I indeed tried `fieldnames()`, but without the command `typeof()`! Perfect!! 🙂
